Children and persons portrayed in
the following examples did not commit any fault. It will be utterly wrong to
think that innocent humans are being punished. It is Not a cruelty by God to
create them this way. Those are employed by God as an example for the rest of
humanity to highlight the punishment that awaits oppressors in hell and to deter
many people from oppression and infidelity. Another reason is to guide us to the
location of genes that cause these impairments and to prevent and treat these
illnesses. .God the Merciful can only be amended with them on the Day of
Resurrection and may repay them the best reward in Heaven.

"We send down in the Holy Book
that which is a healing and a mercy to those who believe" 17:82
